Customize the header & footer

Header

The header is the area on the page above the top navigation tabs.

Background image: You may choose to select an
image from your computer to display in the header section. It will
be set to repeat by default; so be aware of the widest possible
user resolution when designing the header background image.

Overall height: Adjust this value to set the
overall height of the header. This will need to be adjusted to
accommodate the size of the logo set on the Site Settings tab.

Extend header to edges of browser: Selecting
this checkbox will extend the Application Toolbar, header and main
navigation bar to the edges of the browser regardless of the site
width chosen under the Basics tab.
